HENRY A. FROST, OF NEWV YORK, N. Y.

PU LLEY-CLOTHES-LINE TIGHTENER AND FASTENER- SPEGIFICATION forming partof Letters Patent No. 471,251, dated March 22, 1892.

Application filed January 15, 1891. $erial No. 377,925. (ModeL) To allwhom, it may concern".-

Be it known that I, HENRY A. FROST, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and usefullmprovements in Pulley-Olothes-Line Tighteners andFasteners, of which the following is a specification.

My invention relates to certain new and useful improvements in pulleyclothes line tighteners and fasteners, whereby aline may be drawn tautand fastened; and for this purpose it consists of a pulley, over whichthe line is passed and Which is mounted in a suitable housing, thelatter being provided with wings, around which the rope may be wound,and being also provided with a spring-clip thereon to prevent theunwinding of the line, and in the combination,construction, andarrangement of the several parts of which it is composed, as will behereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts aredesignated by similar numerals, Figure 1 is a side view of my deviceapplied to a clothes-line. Fig. 2 is a plan view of the device byitself, and Fig. 3 is a detail of the spring-clip for the line.

The pulley l is contained in a housing 2,.

formed in a single piece of sheet metal, which is bent in its centralpart-and folded back upon itself, thus closing one (the rear) end of thehousing, while the free ends of the sheet metal are bent outwardly andrearwardly, as at 3, forming wings upon the sides of the housing and atthe forward end thereof, around which the line may be Wound. In the rearof these wings spring-wires 4, serving as additional points around whichthe line may be wound, project from the housing and are centrally bentin toward the sides thereof, their ends flaring outward, thusfacilitating the insertion of the line therein.

The spring-clip is constructed as follows: A U-shaped piece 5, formed ofa single piece of wire, projects from the closed rear end of the housingand has its open end secured thereto. A bridge 6, having perforatedends,

through which the parallel pieces of the U- shaped piece pass, slidesthereon and is normally held against the outer end of the U- shapedpiece by the helical spring '7 contained bet-Ween the bridge and theclosed end of the housing. Such being the construction of my invention,it is evident that one end 8 of a rope may be secured to the outer endof the U-shaped piece and that the end 9 of another rope or the oppositeend of the same rope may be passed over the pulley 1, and having beendrawn sufficiently to make the rope or ropes taut on their supports thelast-named end may be wound around the wings 3 and wires 4 in anydesired manner, so as to prevent the loosening of the line, after whichthe loose end, such as 9 of the last-named rope 9 may be passed betweenthe outer end of the U- shaped piece 5 and the bridge 6, where it willbe held by the bridge 6 and spring 7, thus preventing the unwinding ofthe end 9 from around, the wings 3 and wires 4.

Having thus described my invention, what 'I claim is- 1. Thecombination, with a housing having wings thereon, of a pulley pivotedtherein and a spring-clip mounted upon the said housing, substantiallyas described.

2. The combination, with a housing having wings thereon and with apulley pivoted within the said housing, of a U-shaped wire frame securedto the said housing, a bridge sliding upon the said frame, and a springforcing the said bridge toward the outer end of the said frame,substantially as described.

3. The combination, with a housingformed of a single piece of sheetmetal bent back upon itself and having its ends formed into wings at theopen end thereof and with a pulley pivoted within the said housing, of aU- shaped frame secured tothe closed end of the said housing, a bridgesliding on the parallel members of the said frame, and a spring tendingto .force the said bridge away from the housing and toward the outer endof the U- shaped frame, substantially as described.

HENRY FROST.
